CCNA Semester 1 - Skills Based Final Exam - Student Training
Guidelines - Exam Overview and Administration

This exam is for use with regular CCNA classes taught by local academies to high school and college
students. The skills-based exam consists of three parts; 1) Cable Build and Test, 2) Network
Concepts and 3) Network Connection. All three should be completed (total possible of 100 points)
and the total score combined with the Semester 1 online assessment exam to establish a course grade.
Scores from chapter exams and completion of labs as well as points for participation and attendance
may also count toward the final grade.

The guidelines presented here are recommendations and instructors have flexibility in assigning point
values and administering the exam. Students should be made aware of what they will be tested on
early in the course in order to study and prepare adequately for the exam. The exam may be
administered by dividing the class into three groups with each group starting on a different part of the
exam and then rotating as they complete each portion.

Exam Part 1 – Cable Build / Test – (Practical hands-on, Est. time 25 min., 20 Points)
Objective: Build a straight–wired Ethernet cable for connection of a PC to a hub or switch and test it
with a basic cable tester for correct pinouts and continuity. The cable should be CAT 5 and wired to
the T568A or B standards. Length will vary depending on physical conditions. This cable may be
used to connect the PC to the hub or switch used in Part 3 of this exam.

Preparation / Tools: Length of CAT 5 cable, (2) RJ45 connectors, Wire cutter/Stripper tool,
Crimping tool, Basic cable tester or Fluke LAN Cable meter 620.

Exam Part 2 - Network Concepts – (Oral or Written, Est. time 25 min., 30 Points)
Objective: Answer 3 networking concepts questions from a pool of approved questions. Any student
may have to answer any question and will know the questions ahead of time. Responses may be
given verbally to the instructor / proctor or written depending on instructor and student preferences.

Preparation / Tools: List of questions and rubric for assessment. These are found in the instructor’s

version of the Semester 1 curriculum in the Preface, Chapter 0 under First Semester Finals. Rubrics
are also provided to help assess the accuracy and completeness of student’s answers.

Exam Part 3 - Network Connection – (Practical hands-on, Est. time 25 min., 40 Points)
Objective: Connect a PC to a LAN and configure the IP network settings for attachment to an
Ethernet hub or switch that is attached to a router. Determine the subnet mask and host range given
the number of bits borrowed and the subnet number used. Demonstrate connectivity by pinging the
router and opening a web page on it. When the PC is successfully connected to the LAN, problems
will be introduced into the PC and/or network to demonstrate troubleshooting skills. Document the
problems encountered during troubleshooting and the steps taken to correct them.

Preparation / Tools: PC (Mac, Win 9x, NT or 2000) with access to a browser and Control Panel /
Network settings. Straight wired patch cable, hub or switch with router connected. 2514 Router
with IOS 12.0 attached to hub or switch and configured as indicated in the following instructor notes.
A list of potential problems and causes which can be found in the instructor’s version of the Semester
1 curriculum in the Preface, Chapter 0 under First Semester Finals.


Semester 1 Skills Based Final – Part 1 Cable Build / Test
Name: _____________Date: _________
(Total possible Points: 20)

Objective:
Build an Ethernet 10BaseT straight thru cable to connect from a workstation to a hub or switch. Use
UTP cable and wire all eight conductors using the correct wire colors and pins for either a T568A or
T568B. Test the cable with a cable tester to verify continuity, correct pinouts and cable length. This
cable can be used to connect your workstation to the hub or switch for exam part 3.

Directions:
Obtain a piece of CAT 5 cable (depending on use) and two RJ45 connectors. Use a crimping tool to

attach the RJ 45 connectors to the cable. Use a cable tester to test the cable to verify that is
functional. Indicate which cabling pinout standard (T568A or T568B) you will use ___________

1) Are the correct wires in the correct position on pins 1 thru 8? Initial _______ (10 pts)
(Refer to the semester 1 labs for colors and correct pinout)
2) Does cable test OK with cable tester? Initial _______ (10 pts)
(Lights should come on or LCD readout should show continuity)
Points Scored: _______

questions. Sample questions are found in the instructor’s version of the Semester 1 curriculum in the
Preface, Chapter 0 under First Semester Finals. Rubrics are also provided to help assess the student’s
answers. Students will write the questions as assigned in the space provided below. Instructor may
have students answer orally or write answers on the back of this sheet.

Semester 1 Skills Based Final – Part 3 Network Connection
Workstation #: _______
(Total possible Points: 50)







Objective:
Connect a workstation to LAN. Configure the network settings and troubleshoot as necessary. Use a
web browser to connect to router interface 152.20.71.237 and display the web interface. After the PC
is successfully connected to the network, the student should leave and the instructor will introduce
problems into the PC or network which must be resolved and documented in the space provided.
Include the following: symptoms, causes, details of tests done, detailed problem results (from layer 1
testing), detailed solutions.

Instructor notes: A list of potential problems and causes can be found in the instructor’s version of
the Semester 1 curriculum in the Preface, Chapter 0 under First Semester Finals.

Each student should be assigned a workstation number that will become the useable subnet # with
which they perform this assessment. Make sure each student has an appropriate assigned subnet
number before starting. Router configuration allows all workstations to maintain connectivity so

that you may test a class of up to 30 students simultaneously depending on your classroom
environment. Refer to the router configuration at the end of the instructor guidelines to set up the
router. Students must have the ability to alter the IP network settings on their workstations.

Students will be using a class C network 193.5.5.0 which is divided into subnets by borrowing 5 bits
from the network portion of the address. The subnet number assigned is the same usable subnet (1
st
,
2
nd
3
rd
etc.) as their workstation number. The proctor must initial each step. The following example
uses workstation / subnet 2. The default gateway for your host is 193.5.5.1.
Workstation / Subnet number assigned: 2 IP address of your workstation: 193.5.5.17

Semester 1 Skills Based Final – Part 3 Network Connection

Router Configuration Instructor Notes
Use the following configuration to set up the router for the skills test. Use a 2514 router with 2
Ethernet interfaces. ! Both interfaces e1 and e0 need to be connected to the hub. Router password is:
skills1. Router IOS should be at least version 11.2 but preferably version 12.

Students will be prompted for a password when accessing the router through the browser. This
indicates successful completion of the connectivity portion of the Sem 1 skills based assessment.

You may disable the password on the router if you wish for your students to see the web based
interface. (WARNING: this allows the students access to the router configuration) Therefore, you
may wish to wait until after testing is complete to disable the password and show the web-based
interface as a demo instead.

The following router configuration may be 1) keyed in manually at the router console, 2) entered via
the SETUP utility or 3) uploaded using the HyperTerminal Transfer / Send Text File option. Prior to
configuring the router, erase the existing startup configuration file.

Router> enable (Enter current enable password)
Router# erase start (Erases startup configuration file)
Router# reload (Don’t save the existing configuration and let the router reload

Refer to semester 2 labs for the procedures for loading the configuration file from a tftp server or
from HyperTerminal. After the router reboots, you may use the default setup mode or enter config
mode with the following command. Router# config t
